Objectives
By the end of this presentation, all participants will understand:
 The importance of wound assessment and classification.
 How to appropriately document different types of wounds.
 How to appropriately complete sections related to wound care
on OASIS form.
 Strategies to improve delivery of care and reimbursement.
Overview





In today’s home health care market, there is a need for
increased awareness about the management, treatment and
documentation of wounds. Inaccurate documentation and
classification of the wounds leads to :
Inappropriate treatment of the wounds
Delayed healing of wounds
Suboptimal Medicare reimbursement
Decreased quality of care delivery by the agency
Dissatisfied clients
Overview
 The compliance date for implementation of the International
Classification of Diseases, 10th Edition, Clinical
Modification/Procedure Coding System (ICD-10-CM/PCS) is October
1, 2013 for all covered entities.
 ICD-9-CM Pressure ulcer codes
9 location codes (707.00 – 707.09)
Show broad location, but not depth (stage)

Issue
As mandated by the Balanced Budget Act of Medicare , Home Health Reimbursement
is shifted to a prospective payment system. Under this system, payment is based on
the patient’s clinical severity, functional status, and therapy requirements. Home health
agencies are required to submit a completed OASIS : Patient Assessment Form, in
order to receive reimbursement for the services provided to the patient at home.
Unfortunately, 9 out of 10 home health care agencies are unaware that their registered
nurses are not completing the OASIS patient assessment form appropriately; affecting
the agency’s overall reimbursement.

Issue
• Most of the registered nurses who are responsible for completing OASIS
assessment form are not familiar with current wound care classifications and
staging guidelines.
• Wound care terminology used in the OASIS patient assessment form is geared to
be completed by a wound care certified nurse, or a nurse trained in wound care.
• Most of the registered nurses lack in depth wound care knowledge.
• Home health agencies totally rely on billing companies to bill appropriately.
• Lack of wound care nurses involved in the assessment and billing process.
Review of Wounds

Accurate diagnosis and classification of the wound is vital.
Nurses must use national grading / classification guidelines.

Diabetic Ulcer – Wagner’s Grading Scale
Venous Stasis Ulcers – Partial thickness or Full thickness rule
Incontinence Associated Dermatitis – (IAD) fungal Infection

Wound Measurement
Accurate wound assessment is a critical component of effective wound management.
Wound healing is demonstrated by reduction in size, so it is important to measure it
precisely. All wound dimensions must be documented in Length x Width x Depth.
M1310 Pressure Ulcer Length: Longest length “head to toe”.
M1312 Pressure Ulcer Width: Width of pressure ulcer: greatest width perpendicular to
the length.
M1314 Pressure Ulcer Depth: Depth of pressure ulcer; from visible surface to the
deepest area.

Diagnosis, Symptom Control, and Payment Diagnosis
 List each diagnosis for which the patient is receiving
home care and enter is ICD-9-CM code at the level of
highest specificity.
 Diagnosis are listed in the order that best reflect the
seriousness of each condition and support the
disciplines and services provided.
Are these sections filled out accurately ?

 3 – History of falls (2 or more falls – or any fall with injury in the past year)
 4 – Taking five or more medications
 5 – Frailty indicators, e.g., weight loss, self-reported exhaustion
 6 – Other
Can Wounds cause hospitalizations?
www.cms.gov
OASIS : M1034 - Overall Status

 0 – The patient is stable with no heightened risk(s) for serious complications and
death (beyond those typical of the patient’s age).
 1 – The patient is temporarily facing high health risk(s) but is likely to return to
being stable without heightened risk(s) for serious complications and death
(beyond those typical of patient’s age).
 2 – The patient is likely to remain in fragile health and have ongoing high risk(s)
of serious complications and death.
 3 – The patient has serious progressive conditions that could lead to death
within a year.
Can Wounds increase the risks & complications ?

OASIS : M1240/M1242 - Pain
Pain related to wounds must be assessed and documented
appropriately.
(The Wong-Baker FACES Pain Rating Scale)
www.cms.gov
Home Care Best Practice Model
 Patients with skin problems or wounds or high risk for developing wounds shall be
assessed by a wound care certified nurse.
 Digital images of wounds to be part of the medical record. Weekly updates are
recommended.
 Weekly measurements of wounds shall be completed and documented in the
medical records.
 Electronic medical record (EMR) is preferred over paper charting.
 Contracted billing company must be evaluated for appropriate billing practices.
